I had a situation with a disscusion that was frustrating in a funny way.
I work outside with a group of co-workers and we start our shift very early in the morning. The sun had not risen yet. Two co-workers where looking up at the sky, pointing at it and having somewhat of a lively debate. I walked over and found that they where discussing whether what they where looking at in the night sky was a star or a helicopter. Well I looked at it and found it was a star. Believe me, a payed attention to this darn star till the sun came up and it never moved. We told the guy it was a star, but he would'nt believe us. It's been a month and still to this day he will still say it was a helicopter.
